LAMINARY VALVE.

Application filed February 27, 1915.' Serial N 0. 10,963.

To all whom may concern:

Be it known that I, .GEOBGE J. BRYEN, a citizen of the United States, and resident of Duquesne, Allegheny county, Pennsylvania, have invented a new and useful Laminary Valve, of which the following is a'specifica- My invention has relation to valvesof the class used on compressors, blowing engines, and similar apparatus employed in com: pressing air or other gaseous fluid, and while not restricted to such use, more particularly relates to the class or type of valve employing a spring in seating the valve.

One object of the invention is to provide a laminary valve of novel construction whereby the number of parts in the valve is lessened, its strength and stiffness are materially increased, its life and wearing qualities are lengthened, and liability of distortion or breakage of the valve while in service.

is materially reduced. 7

Another object of my invention is to provide a laminary valve of improved constructionwherein the parts of the valve, including the spring therefor, are formed integrally from the fiat metal disk.

Still further objects of my invention will become apparent as it is to be more fully described hereinafter and specifically pointed out in the appended claims.

Referring now to the accompanying drawings forming part of this specification, Figure 1 is a plan showing a laminary valve constructed and arranged in accordance my invention. Fig. 21s a sectionalwith side elevation showingthe laminary; valve of Fig.1, the section being taken .onthe line IIII of Fig. 1. Fig. 3 is a sectionalside elevation similar to that of Fig. 2, showing a modified form of laminary valve constructed in accordance with this invention.

Fig. 4 is aplanshowing the outline of the thin flat metal blank from which the valves of Figs. 1, 2 and 3 are made, preparatory to the first forming step of my improved method. Fig. 5 is a sectional side elevation shbwingthe blank at the completion of the first forming or cupping step, and the forming dies-employed in this step of my improved method. Fig.6 is a similar side elevation showing the blank at the completion of the next step of the method, and the dies'employed therewith. Fig. 7 is a sectional side elevation, similar to that of Figs. 5 and 6, showing the blank as formed in this Specification of Letters Patent.

step of my method, and the dies employed in connection therewith. Fig. 8 isa similar sectional sideelevation showing the neXt step of'forming the cupped blank, and the dles used in carrying out this step of my improved method.- Fig-9 is a sectional side elevation similar to that of Fig. 8 showing the, finalbending step employed-in forming the cuppedblank, and the dies used in this step of my method. .Fig. 10 is a plan showing a valve,,valve seat, and valve stop, as assembled for use. Fig. 1-1 is a sectional side elevation showing the assembled valve, valve seat, and valve stop, the valve being shown in seated or closed position. Fig. 12 1s asectional side elevation similar to that-of Fig. 11, the valve being shown in lifted or open positioninstead of in closed position, as in Fig. 11.v

As will be seen in Figs. 1 and 2, the laminary valve comprises a layer 2 forming the seat of the valve, which is integrally joined at its periphery 3 to the layer 4. A central opening 5 is provided in the layer 2, and a plurality of openings 6 surround the smaller central opening or hole 7 in thelayer 4. A spiral groove is provided in. the layer'4 between the holes 6 and the periphery 3.-of the valve so as to form a spring 9 bywhich the valve is seated and is yieldingly held in seated position.

In the valve shown. in Fig. 2 the lower layer or seat 2 of the valveextends parallel with the top layer 4, and is slightly separated therefrom. In the valve shown in Fig. 3 the top layer 4 and lower layer 2 are pressed closely together and may be pressed into close contact adjacent to the periphery 3 thereof, the valves of these figures otherwise being similar in construction.

In making the valveof Figs. 1 and 2 in accordance with. my improved method,

top-die 13, which has. a projection 14 on its 1 lower face (to enter the central opening 7 in the disk) is then caused to force the flat disk 10 through the opening 12 in the lower die 12 and form the. disk into a capped blank having a fiat end 1.5 with a cylindrical 7 and after placing the blank in the recess.

flange 16 on its periphery. blank, formed in the operation which has just been described, is then placed in position on the bottom die 17 of the second set of dies, 17 and 1S, (as is shown in dotted lines in Fig.6). The top die 18 is then actuated to force the cupped blank through the opening 19 in the. bottom die 17, this operation squaring or further shaping the blank by reducing the size of the fillet 20 connecting the cylindrical flange 16 with the flat end 15 of the'blank, and increasing the width or height of the flange 162 The blank formed in the dies of Fig. 6 is then removed .to a third set of dies (shown in Fig.

22 of the bottom die 23, the frusto-conical recess 24 in the face of the top die 25 of this set isbrought into engagement with the blank so as to force the flange 16 inwardly into position extending substantially at an angle of 45 degrees to the horizontal. The now frusto-conical flange 16 will be upset or thickened somewhat in this step of the valve forming operations. The blank is then removed to the next setof dies 26 and 27 (shown in Fig. 8) in which the flange 16 is further bent orflattened by the frusto-- conical recess 28 in the top die 27 while the blank issupported in the recess 29 inthe bottom die 26 so asto extend at an angle somewhat less than 45 degrees to the horizontal. The blank of Fig. 8 is: then trans.

' ferred to another set of-dies 30 and 31'having registering recesses 32, 33, and'the inwardly inclined-flange 16 which ultimately forms the lower layer or seat 2 of the valve,

. is then pressed inwardly within these recesses until its outer face extends parallel to the outer face of the other layer of the valve which forms the top layer 4 in the finished valve.- In this operation, the two layers 2' and 4 are not forced closely intoengagement, so as to form the valve of Fig. 2.

"When it is desired to make a valve like that shown in Fig. 3, the blank is taken from'the dies of Fig. 9 tea modified form of dies similar to those shown in Fig. 9, having recesses 32, 33, arranged to press the adjacent faces of the two layers 2 and 4 of the metal forming the valve into close contact, as is shown in the valve of Fig.3. The valves, after being formed in this way, are then faced on the valve -seat. layer-2, the

spiral groove'S is cut to form the spring- 9, and the openings 6 are provided in the top layer 4 of the metal forming the valve, the spring 9 forming the means by which the valve is "seated and yieldingly heldin seated or closed position on the adjoining face of'a valve grid. After the spiral groove 8 is provided in the valve the metal forming the spring 9 is'bent upwardly so as to give The cupped it a permanent set, and cause it toremain in theseparated position shown in Figs. 2 and 3, so that when the valve is secured in as sembled position later, as shown in Figs. 10 and 11, the spring 9 will act to hold the layer 2. of the valves in closed position, as shown in these figures. The valve is then tempered, andif necessary, the seating face of the bottom layer 2 of the valve is machined or faced, and the valve is in readiness to be assembled for use.

The valve grid 34 (see Figs. 11 and 12) which is of ordinary known construction,

tends through the' opening 7 in the valve I spring 9, and registering openings in the center of the valve grid 34 and stop 39, to- -'hold the parts in assembled relation, and the valve stop 39 is provided with a plurality of openings 41 which register with the simis larly shaped openings 6 in the top layer 4 of'the valve. A series of the grids 34, each having a valve and valve stop'in assembled position thereon, are'as'sembled in the heads Y of the cylinder of the compressor, blowing engine, or other apparatus, in the usual known manner.

The advantages of my invention will be 7 apparent to those skilled in the art. A valve of improved wearing qualities and increased strength and rigidity is provided without any, or with slight, increase in the cost of manufacture.

By means of my improved.

method the valve is easily and quickly made. a

a plurality of grooves may be used, and
